Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to evaluate the safety and efficacy of a novel CD19-CART in the treatment of refractory or recurrent ALL.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Chimeric antigen receptor T cell (CART) is a kind of engineered immunotherapy by transferring an artificial antigen binding receptor and also intercellular co-stimulating molecules into T cells. This kind of engineered T cells gains the ability to recognize antigen specific tumor cells and initiate the killing process in a HLA-independent way. CD19 is the specific cellular marker of B lineage acute leukemia (B-ALL), thus CD19-CART will be efficient in treating B lineage ALL. The investigators have constructed two kinds of CD19-CART. One is equipped with a murine CD19 scFv (single-chain variable fragmentt), while the other with a humanized scFv. This study aims to evaluate the safety and efficacy of both murine and humanized CD19-CART in treating refractory or recurrent ALL.
